NATURALIST'S GUIDE TO THE AMERICAS 



generally scattering, both as to numbers 

 and species. Throughout Utah and 

 Nevada the wild life is decidedly below 

 normal and herbaceous vegetation has 

 been considerably affected by grazing 

 in many places by decided over-grazing. 



NATURAL AREAS 



Ashley National Forest (Utah and 

 Wyoming) 



The Ashley Forest (980,135 acres) 

 is located upon the east end of the Uinta 

 Range and consists of a broad mountain 

 range with a high barren east and west 

 backbone. The whole central part is 

 in a nearly virgin condition due to 

 light grazing that results from very 

 dense timber and the high barren alpine 

 region. The leading types in order of 

 extent are: Lodgepole pine 45%, Engel- 

 mann spruce 14%, barren 13%, grass 

 6%, western yellow pine 5%, sagebrush 



5%. 



Deer, elk, and bighorn sheep range in 

 the northeastern part of the Forest. 

 At high elevations there are many 

 glacial lakes of considerable interest 

 from a geological standpoint. The 

 streams in the high mountains contain 

 a pure stock of native trout.

Boise National Forest (Idaho) 



The Boise Forest (1,062,698 acres) 

 lies in central Idaho upon a granite 

 uplift deeply cut by canyons. It is 

 largely a virgin Forest. Grazing is 

 general although not heavy. Timber 

 cutting is mostly around the edges and 

 in the vicinity of several mining camps 

 on the Forest. The chief types are: 

 subalpine 37%, Douglas fir 24%, western 

 yellow pine 19%, grass 10%, lodgepole 

 pine 4%. 



The game preserve in the northeastern 

 part of the Forest on the South Fork 

 of the Payette River is well stocked with 

 deer, mountain goat, and elk.

Bridger National Forest (Wyoming) 



The Bridger Forest (698,325 acres) 

 lies upon the west slope of the Wind 

 River Range, which is high and rugged 

 and is largely virgin. At the south tip 

 of the Forest and also at the north end 

 are State Game Preserves. Grazing is 

 general. Timber cutting is very limited. 



There are considerable numbers of 

 big game such as bighorn sheep, elk, 

 and grizzly bear well distributed over 

 the Forest. Geologically this area is 

 very interesting, containing fully 500 

 lakes formed principally by glacial 

 action. At the head of the streams 

 rising in the Wind River Range there 

 are a few living glaciers.

Cache National Forest (Utah and Idaho) 



The Cache Forest (770,131 acres) 

 lies mainly on the north extension of the 

 Wasatch Mountains with minor divi- 

 sions upon other small north and south 

 ranges in northern Utah and southern 

 Idaho. The Forest has an absolutely 

 protected area of about 15 sq. mi. in 

 the lower part of Logan Canyon. The 

 Forest is completely grazed, except 

 for about 25 sq. mi. in the Pocatello 

 Division where grazing is prohibited 

 upon the Pocatello municipal water- 

 shed; and is all cut over except for a 

 small area at the north end now under 

 sale. In this Forest are three 5-acre per- 

 manent sample plots one of which is to 

 be maintained in its natural condition 

 except that grazing is not restricted. 

 The south end of the Forest is within 

 a State Game Preserve. The major 

 types are: brush 34%, sage 20%, aspen 

 18%, Douglas fir 11%, subalpine 5%, 

 lodgepole pine 4%, Engelmann spruce 

 3%, juniper 3%. The northern limit 

 of the range of Abies concolor is on this 

 Forest.
